Microsoft Cognitive Services is a collection of APIs that are available to developers to make their applications more intelligent and engaging. This set of services expands on our evolving portfolio of machine learning APIs and lets developers easily add intelligent features to their solutions. Speaker Recognition API is now in public preview. Its features include:

Speaker verification, using voice for authentication. The API can be used to power applications with an intelligent verification tool. For example, if the speaker claims a certain identity, you can use their voice to verify this claim.

Speaker identification, to recognize who is speaking. The API can be used to determine the identity of an unknown speaker. Input audio of the unknown speaker is compared to a group of selected speakers and if a match is found, the speaker’s identity is returned.

Speaker Recognition API is available as a stand-alone service. Public preview pricing went into effect on May 2, 2016. For more information about pricing, please visit the Cognitive Services pricing page.
